Specification of Letters Patent.

Patented Aug. 29, 1905.

Application filed January 27,1905. SeralfNo. 242,896.

To al?, whom, it may con/cern:

Be it known that we, CHARLES O. TowNE, residing at Torrington, county ofLitchfield, and JOSEPH H. WooDwARD, residing at Waterbury, county of'New Haven, State of Connecticut, citizens of the United States, haveinvented a new and useful Stopper for Water- Bags, of which thefollowing is a specification.

Our invention has for its object to provide a non-detachable stopper forwater-bags-that is, a stopper having a valve which may be r0- tated toopen or close the bag, but without removal from the thimble.

It is of course well understood that the stoppers of water-bags asordinarily constructed must be entirely removed from the neck in orderto open the bag. This is a serious inconvenience, as the Stoppersfrequently get mislaid and cannot be found when wanted.

We are aware that it is common to provide detachable stoppers forwater-bags with means for attaching them to the handle-loop,` and otherStoppers for water-bags have been attached to flaps or tabs. So far aswe are aware, however, the constructions have been such that the stopperwas necessarily removed from the neck in order to open the bag.

Our present invention does away with the objections to the variousstyles of water-bag Stoppers now in use and provides a stopper that isnot removed from the neck of the bag in opening, is very convenient inuse, is easily and quickly operated to either open or close the bag, iscertain in operation, effecting a perfectly tight closure of the bag,and is sirnple and inexpensive to make, so that it may be placed on themarket without advance in price over the inferior devices for the samepurpose now in general use. 40 In the accompanying drawings, forming apart of this specification, Figure 1 is a vertical section showing ournovel stopper in place in the neck of a water-bag, the valve being inthe closed position; Fig. 2, an inverted plan View of the valvedetached; Fig. 3, a plan view of the thimble detached with thespringring in place; Fig. 4, a perspective of the spring-ring detached;Fig. 5, a plan view of a stopper complete and showing a variant mode ofretaining the valve in the thimble; and Fig. 6 is a transverse sectionof a stopper complete, showing still another mode of retaining the valvein the thimble.

Our novel stopper comprises, essentially, a thimble 10, adapted forattachment in the neck of a water-bag in the usual or in any preferredmanner, said thimble being provided with a central opening 19, aninternal screw-thread 11, which may be rolled or cut, as preferred, andwith a ledge or shoulder, which serves as a valve-seat and is indicatedby 12, and a valve 13, which is connected by arms 14 to a threadedsleeve 15, which is adapted to engage the thread upon the thimble.

In Figs. 1 and 3 we have shown the thimble as provided near its upperend with an internal circumferential groove 16, which is adapted to beengaged by a spring-ring 17 to limit the upward movement of the sleevean'd prevent its detachment from the thimble.

18 denotes a rubber washer, which is preferably placed upon thevalve-seat and is provided with a central opening corresponding withopening 19 in .the thimble. The valve is held centrally in the sleeve bymeans of the arms, which are shown as made integral with a handpiece 20,which is provided for convenience in operation. The open space betweenthe valve and the sleeve is indicated by 21.

In assembling the form illustrated in Figs.

` 1 and 3 the threaded sleeve carrying the valve is turned into thethimble and is secured there by placing spring-ring 17 in the internalcircular groove near the upper end of the thimble. To close a water-bag,the valve is simply turned down upon the valve-seat, the interposedrubber washer preventing the possibility of leakage. Toopen the bag, thevalve is simply raised from the valve-seat by rotation ofthe sleeve bymeans of the handpiece, the'upward movement of the sleeve being limitedby its engagement with the spring-ring. When the valve is raised, thebag may be emptied of its contents by inverting it, the water passingthrough opening 19 in the valveseat and out between the valve and thesleeve.

If preferred, instead of a circular groove and a spring-ring to retainthe sleeve and valve in place they may be retained in the thimble bymeans of lugs 22, turned inward from the top of the thimble, as clearlyshown -in Fig. 5, or by means of bosses 23, struck IOO inward from themetal of the th'imble, as clearly shown in Fig. 6.

Having thus described our invention, we c1aim- 1. A stopper forwater-bags comprising a thimble adapted for attachment to the neck of abag and provided with an internal screwthread and a valve-seat having acentral opening, a valve adapted to engage the seat and a sleeve,threaded to engage the thimble, to which the valve is connected, leavingan open space between the valve and the sleeve for the passage of water.

2. A stopper for water-bags comprising a thimble adapted for attachmentto the neck of a bag and provided with an internal screwthread and aValve-seat having a central opening, a valve adapted to engage the seat,a sleeve threaded to engage the thimble and a handpiece connected to thevalve and to the sleeve, leaving' an open space between them.

3. A stopper for water-bags comprising a thimble adapted for attachmentto the neck of a bag and provided with an internal screwthread and avalve-seat having a central opening, a rubber washer engaging the seatand having a corresponding opening, a Valve, a sleeve threaded to engagethe thimble and a handpiece connected to the valve and to the sleeve.

In testimony whereof we affix our signatures in presence of twowitnesses.

CHARLES O. TOWNE. JOSEPH H. WOODWARD.
